VALVE.

To all whom itma'y concern:

Be it known that I, HUMPHREY OLEARY, citizen of the United States, residing in the c ty and county of San Francisco and State of California, have invented new and useful Improvements in Valves, of which the following is a specification.

This invention relates to valves, ticularly to angle valves.

The object of the present invention is to and par-- signed as to permit one of its elements to swing or swivel freely about an axis; and also to provide a valve which may be convertedfrom a swivel valve into a stationary valve; and toprovide means whereby the valve may be leakage.

thereby prevent kinking of the hose when the latter is moved about, for instance, over a lawn or in a building. The valve is equally adaptable to control. the passage of fluid or liquid and may be made tight-so as to prevent the turnable member from rotating when it is desired to so mount it;

' In the present embodiment of my invention A is a valve body adapted to be fixedly secured to a stand pipe a.

2 represents a swivel union embracing andturnablc on the body A. The union .2 may be cylindrical or globular in shape, and is provided with a threaded portion 3.to which may be attached a bonnet 4: in which is guided a valve stem 5, having a handle at its upper end and a valve'disk 6 at its lower end. A suitable packing gland 7 is provided and attached to the upper portion of the bonnet 1 to prevent leakage of fluid or liquid past the valve-,stem. The swivel union 2 is provided with"a' projection 8, whereon may Specification of Letters Patent. Application filed April 6, 1911.

be attached a hose or pipe through which fluid or liquid admitted into the body A may pass. The lower portion of the union 2 is' p I provided with a rearwardly projecting, conica'l shoulder or seat 9 which is adapted to cooperate with a corresponding rearwardly projecting, conical seat 12 on thevalve body A. Within the body A is a valve seat 11 for the valve 6. The body A is provided at its upper end with an upwardly extended portion of reduced diameter, which is provided with transverse ports 11 through which the fluid admitted past the the union 2. the body A below. the conical seat 12 is threaded to receive a reversible nut 15 adapted, when the device is to be used as a swivel valve 6 may enter A portion of the exterior of valve as in Figrl, to be screwed upagainst a shoulder 16 formed upon the exterior of the body .A.

The valve as thus described is capable of being mounted so that the union 2 may be swiveled about its axis. By reversing the nut 15, as shown in Fig. 3, the union 2 may be rendered stationary and hermetically since the and allows the nut to up against the seat 12.

In adapting the valve for swiveling operation the nut over the screw threads 14, is carried against jam the swivel snug 15, when advanced upwardly the shoulder 16 which is sufficiently spaced I below the conical shoulder 9 as to allow the union to swivel or turn about the body A circumferentially so that when a flexible deice, such as a hose, has been attached to the projection 8 the coupling or union 2 may be moved ina complete circle about thevalve without kinking the flexible connected portion whatsoever. When the valve isto be. adapted in a stationary position, as for instance when it is erected in a system of immovable pipes in system, it is then ,desirable that the union 2 be rendered absolutely stationary and hermetically sealed. In this case the nutl5 is placed upon the lower portion of the valve body A with the counter-bore or sunken portion 17 facing the shoulder 16; The diam: eter of the counter-bore 17 is slightly larger than the diameter when the nut 15 is advanced over the screw threads 14 the surface 18 of the nut bears of the shoulder 16. Thus uponthe transverse end of the union 2 and thus draws the conical faces 9 and 12, formed respectively on the union 2 and the valve body A, into a close juxtaposition forming a water tight joint.

One of the particular advantages in providing an angle valveof this construction is that. in erecting a pipe system the union 2 can be attached at its projection 8 to a pipe or other structure which has been permanently secured in place, and these two members can be screwed together until a perfectly tight joint is formed between them. Then a connection can be made tothe-lower threaded portion of the valve body A and can be rendered absolutely tight by turning the body A. This cannot be accomplished with ordinary reciprocating valves because of the fact that when two pipes or conductors meet at an angle, one or the other of the meeting conductors to which the valve is to be connected is either generally left slightly loose and must be leaded, or it is too tightly screwed into the valve threads, thus stripping the threads and producing a leaky joint. By this valve the conductors can be coupled to the union 2 and to the lower portion of the valve body A respectively and screwed to a good, tight-joint. While the coupling is being made to the valve body A the latter may be allowed to turn freely within the union 2. After the joint has been completed between the conductors to be attached to the valve and a good joint made, then the locking nut 15 is advanced over the valve body A to permanentl seat the conical shoulders 9 and 12 and orm a hermetically tight joint. When the valve is erected for a swiveling action leakage is prevented between the working joint made at 9 and 12 by reason of the fact that the passage of the fluid or liquid admitted into the union 2 is eifective, by the pressure of the same against the bonnet, tofirmly seat the conical surfaces 9 and 12, thus making a tight joint but not-preventing the swiveling of the union 2 on the valve body.

Having thus described my invention, what I Copies of this patent may be obtained for ciaaaa' I claim and desire to secure by Letters Pat- 1., 1A swivel valve,comprising a fixed body portion having a lower' nduction port and -an'upper eduction port, and provided on its exterior surface with an upwardly extending conical seat, a swivel union with a conical seat surrounding and bearing upwardly against the body seat, a bonnet and valve carried. by the swivel union, and a nut on the body and engageable upwardly against the swivel union. 1 V

2. A valve comprising a union having an internal conical shoulder, a separable chambered valve body having an external conical shoulder to seatdownwardly upon the aforesaid shoulder in the union,,a nut adjustable upon the valve body below the union, a closure, for the union, and a valve disk and stem adapted to seat upon said body and guided in said closure. v 3. .A valve comprising a chambered valve body adapted to be secured. to a fluid conductor having an external shoulder, a'union swivelly mounted uponsaid body, a closure for said union, and means for sustainingthe turnable union upon the-valve body, said means comprising a reversible nut adapted to seat against the said shoulder and allow motion of the union relatively to the seat. 4. A valve comprising a chambered valve body adapted to be fixedly mounted, a-union and its bonnet turnable about-the fixed body,

a valve disk and stem movable within the].

union, and means whereby the union may be immovably seated against the. valve body, said means including a reversible nut having a counter-sunk face adapted to be.

screwed over the exterior of the fixed valve body and engage the end of the union to seat the union firmly upon the valve body.

In testimony whereof I have hereunto set presence of. two subscribing my hand in the witnesses. V. i
